Objective To Validte the Yeliabil of left ventricle ejection fraction(LEF) measured by reconstructed impedancecardiography(RICG).
目的验证重建心阻抗图测量左室射血分数(LEF)的可靠性。

However, impedancecardiography, which has been shown to be a reliable alternative to cardiac catheterization, offers a noninvasive method of screening such patients.
但心阻抗图已被证实是一个可信赖的代替心导管术的方法,提供了一个非侵入性方法来筛选这样的病人。
